I hate to do this, but is it possible to port this mod to 1.21? Thank you!

I honestly had no clue 1.21 was out yet. I´ll take a look at it later - hopefully! :)

Good thinking. Hope it get released soon. 👍

It´s available on Jenkins (No Forge for now, cause of Architechtry Loom not support Forge for 1.21 yet) :)

I´ll get it on CurseForge later
